50 POINTS IF YOU ANSWER CORRECTLY!

Problem 4:  Option C, 32

Problem 5:  You need to have the 2 and the x combine.  Make the table 2x than 16.

Problem 6:  x = 17

Problem 7:  She drew a 2, x and an 16.  Instead you must have 2x and 16.  2x + 16 = 50

Step-by-step explanation:

Problem 4

2 + x + 16 = 50

x + 18 - 18 = 50 - 18

x = 32

 Option C, 32

Problem 5

You need to have the 2 and the x combine.  Make the table 2x than 16.

 You need to have the 2 and the x combine.  Make the table 2x than 16.

Problem 6

2x + 16 - 16 = 50 - 16

2x / 2 = 34 / 2

x = 17

 x = 17

Problem 7

She drew a 2, x and an 16.  Instead you must have 2x and 16.  2x + 16 = 50

She drew a 2, x and an 16.  Instead you must have 2x and 16.  2x + 16 = 50

50

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
